How to use PHPMailer to send emails in php?

PHP is a popular server-side programming language that is often used to create dynamic websites and web applications. PHPMailer is a very popular email sending library in PHP, which provides a convenient and easy-to-use interface for sending emails in PHP. Next, this article will introduce in detail how to use PHPMailer to send emails.

First, we need to download the PHPMailer class library. It can be downloaded from the official website of PHPMailer (https://github.com/PHPMailer/PHPMailer) or other code hosting websites. After the download is complete, copy the PHPMailer class library file to your project directory, or install it directly using Composer so that you can reference it in your program.

Before referencing PHPMailer, you need to include statements referencing the PHPMailer class in your PHP file. The statement is as follows:

require_once('/path/to/PHPMailer/src/PHPMailer.php');
require_once('/path/to/PHPMailer/src/SMTP.php');

This will make the PHP file contain the PHPMailer class and SMTP class. Next, we need to instantiate the PHPMailer object. The sample code is as follows:

$mail = new PHPMailerPHPMailerPHPMailer();

After instantiating the object, you need to set the parameters of the SMTP server. Additionally, you need to set the sender's authentication and related email parameters. Below is a sample code snippet that shows how to set up the SMTP server and related parameters:

$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'you@example.com';
$mail->Password = 'your email password';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;

In this example, we have set up the SMTP server and related parameters. The isSMTP method tells the PHPMailer class to use the SMTP mailer, and the Host attribute sets the SMTP hostname. The SMTPAuth attribute indicates that the SMTP server requires identity authentication, and the Username and Password attributes set the SMTP username and password respectively. SMTPSecure is set to ssl, which means sending emails through SSL encryption. Finally, set the SMTP port number to 465.

Next, you need to set the parameters for your email. The sample code is as follows:

$mail->From = 'you@example.com';
$mail->FromName = 'Your Name';
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->addReplyTo('you@example.com', 'Your Name');
$mail->isHTML(true);
$mail->Subject = 'Test Email';
$mail->Body    = 'Test email message body.';

In this example, you need to set the necessary parameters of the sender of the email, such as the sender name and address and the recipient name and address of the communication email. You can also set the address and name of the reply email, and set the format and subject of the message body. The isHTML attribute sets whether the email is in HTML format.

Finally, you only need to call the send method to send the email. The sample code is as follows:

if (!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent.';
}

In this sample code, if the send method returns false, it means that the email failed to be sent. In this case, you can output the Mailer Error message for more information. If the send method returns true, the email is sent successfully.

Summary:

PHPMailer class library is a very powerful PHP email sending class library that provides a simple and flexible API that can help you quickly start sending emails in PHP. This article explains how to use PHPMailer to send emails to recipients. You can adapt and extend the sample code to your own needs to implement functionality that matches your actual needs.
